How NOT to find an artist:
Do not look for either professional artists, or an artist that has done a lot of game design work in the past. The problem with artists who do this as their full time job is that they’re usually expensive. Compared to what you can find through art sites, these guys tend to cost an arm and a leg. Artists who have done a lot of game design work are also bad for a similar reason, they know how much flash games can earn so they expect a decent percentage of the profit.
